For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. How hard is it to reach a businessperson by phone? Let p be the proportion of calls to businesspeople for which the caller reaches the person being called on the first try. LAUSE SALT (a) If you have no preliminary estimate for p, how many business phone calls should you include in a random sample to be 80% sure that the point estimate p will be within distance of 0.07 from p? (Round your answer up to the nearest whole number.) phone calls (b) A report states that businesspeople can be reached by a single phone call approximately 23% of the time. Using this (national) estimate for p, answer part (a). (Round your answer up to the nearest whole number.) phone calls

The Student Health Center at NCSU would like to conduct a survey to estimate the proportion of NCSU students who have smoked marijuana in the past month. The Student Health Center would like to estimate the population proportion p to within .04 with 95% confidence. 1. What sample size is required if the Health Center has no knowledge of the approximate value of p? 2. The Health Center discovers the results of a previous survey that estimates p to be about .35. Use this additional information to calculate the sample size required to estimate the population proportion p to within .04 with 95% confidence.

The high price of medicines is a source of major expense for those seniors in the United States who have to pay for these medicines themselves. A random sample of 1600 seniors who pay for their medicines showed that they spent an average of $4300 last year on medicines with a standard deviation of $500. Make a 90% confidence interval for the corresponding population mean. Round your answers to cents. i to $ i %24
